I am trying to create an easy legend with bubbles for a Bubblechart.

The legend should have the BubbleSizes -> {.02, .05}, for the scores 3 to 8 and ranging with the rainbow colors. Basically this but with bubbles of increasing size, instead of squares: enter image description here

Is there any easy way to do this???

This is my code right now:

legend2 = 
 BarLegend[{"Rainbow", {3, 8}}, 5, 
  LegendLabel -> Style["Happiness Score", 16], LegendLayout -> "Row"]
$\endgroup$

dt = Range[3, 8];

SwatchLegend[ColorData["Rainbow"] /@ Rescale[dt], 
  dt, 
  LegendLabel -> Style["Happiness Score", 16], 
  LegendLayout -> {"Row", 1}, LegendMarkers -> "Bubble", 
  LegendMarkerSize -> 5 dt] 

enter image description here

Change the second argument from dt to Rescale[dt, MinMax@dt, {.02, .05}] to change the labels:

    $\begingroup$ Can also use PointLegend and omit LegendMarkers. $\endgroup$ – Rohit Namjoshi Jan 8 at 17:54
  • $\begingroup$ Is there a way to make the numbers smaller? LegendMarkerSize only changes the size of the bubbles $\endgroup$ – Faye Drew Jan 8 at 19:27

  • $\begingroup$ Now, how did you figure out there is such "Bubble" markers? @kglr ? :) $\endgroup$ – MinHsuan Peng Feb 6 at 22:25

    $\begingroup$ @MinHsuanPeng, it is in the docs: SwatchLegend >> Options >> LegendMarkers $\endgroup$ – kglr Feb 6 at 22:43
